Ingredients

Banana Bread Bars

  • 2 cups ripe bananas
  • 1½ cups white sugar
  • 1 cup sour cream (can sub plain yogurt)
  • 1/2 cup softened butter (unsalted)
  • 2 eggs
  • 2 teaspoons vanilla
  • 2 cups flour
  • 1 teaspoon baking soda
  • 3/4 teaspoon salt
  • 3/4 teaspoon cinnamon (optional - this is my addition)

Chocolate Frosting

  • 1/2 cup melted butter (unsalted)
  • 2/3 cup cocoa powder
  • 4-5 cups powdered sugar
  • 1 teaspoon vanilla
  • 3-4 tablespoons milk

Instructions

Banana Bread Cake

  • Preheat oven to 350°F. Spray a rimmed 12x17 baking sheet with nonstick cooking spray (and I like to line with parchment paper also).
  • Cream sugar, butter and sour cream.
  • Add eggs, vanilla, and mashed bananas. Mix well.
  • Combine dry ingredients then add to wet mixture. Mix until combined.
  • Pour batter into pan and bake for 28 minutes at 350°F.
  • Before removing from oven, make sure top of cake springs to the touch.
  • Remove and let cool before frosting.

Chocolate Frosting

  • Melt butter. Pour into a stand mixer with the cocoa powder and mix using the paddle attachment until combined.
  • Slowly, add the powdered sugar, alternating with a tablespoon of milk, until you reach the consistency desired. Add vanilla and mix until incorporated.
  • Once banana bars are cold, spread chocolate frosting across the top. Cut into squares and enjoy!
